It is the TANAKA pipe automatic welding machine that can weld a pipe from φ10.5 to φ406.4mm by several kinds of welding heads.
By concentrating TIG arc with a special nozzle, "PlasMan" is a pipe automatic welding machine that can use the plasma arc heat source of a high energetic density. The welding parts of less heat distortion is obtained.
"O2 Monitor" is the measuring device of low concentration of oxygen to measure the remaining oxygen density in side pipes when stainless piping is welded. Low concentration O2 at 1000ppm or less can be measured.
